you would be hard-pressed to find a late-model processed food that isn’t made from corn or soybeans. In the typical formulation, corn supplies the carbohydrates (sugars and starches) and soy the protein; the fat can come from either plant. (Remember what George Naylor said about the real produce of his farm: not corn and soybeans but “energy and protein.”) The longer the ingredient label on a food, the more fractions of corn and soybeans you will find in it.
